Determination of 5 Rare Earth Elements in Geological Samples by Microwave Digestion-Inductively Coupled Plasma Emission Spetrometry
Aiming at the determination of rare earth elements in geological samples,a method combining microwave diges-tion and inductively coupled plasma emission spectrometry (ICP-OES) was proposed to determine La,Ce,Nd,Th and Y in complex samples. Prepare samples using microwave digestion and evaluate the accuracy of the determination results through spiked recovery experiments at two concentration levels. The experimental results indicate that this method can effi-ciently and accurately determine the content of rare earth elements in complex geological samples. Finally,this article sum-marizes the main conclusions and significance of the study,emphasizing the potential application of this method in geologi-cal science research.
